What is the center of all human life? Men and women center their lives around things like wealth, power, religion, and more. They look to these things to give them meaning and joy but Scripture has a very different answer to this question. God’s word shows that it is the person of Jesus Christ who is essential and foundational to all human existence. His coming to earth and dying for sinners is the most important fact because it is only through Him that anyone can be saved. There are even those who claim to be Christian, yet replace Jesus with their own works, the church, or something else. This is a fatal error because it takes the focus off of Jesus Christ and turns it to a secondary thing. The only truly happy and blessed life is that which is focused and centered on the true Jesus Christ who has died in order to save sinners. This sermon from Dr. Martyn Lloyd-Jones on John 3:30 titled “Complete in Him” forces all to ask themselves: “is Jesus the center of my life or am I trusting in something lesser?” All must begin with the glory and weightiness of God as He has revealed Himself in Jesus Christ and center their life on this Christ.
